FIELD OF THE INVENTION

The utility model relates to the technical field of meat tenderizers, and particularly discloses a meat tenderizer that can be disassembled and is convenient to clean.

BACKGROUND OF THE INVENTION

Meat ingredients have become an indispensable type of dishes in people's daily diet because they are rich in indispensable nutrients such as protein for humans. Since the muscle fibers of meat, especially those of red meat such as beef, are relatively rough and hard, the meat is not easy to be tasty and well-cooked upon cooking. To solve this problem, people have begun to process meat with meat tenderizers. Meat tenderizers are a kind of appliances with blades at their front ends, wherein the blades are pierced into meat to cut meat fibers, so that meat products can be better flavored when cured, and are easier to be cooked. Some meat tenderizers also have baffle plates at their front ends. However, meat tenderizers in the prior art are often nondetachable, which makes it difficult to clean the meat tenderizers, especially their blades. The blades that have not been washed clean are liable to breed bacteria which have an adverse effect on food. Some meat tenderizers also have a problem that water is retained in housings but cannot be discharged.

As shown in FIGS. 1 to 3, a detachable and easily cleanable meat tenderizer includes a housing 1, a blade holder 2, a blade 3 and a baffle plate 4.

The housing is divided into a first housing 11 and a second housing 12, wherein the first housing 11 is provided with an insertion hole with two open ends, the second housing 12 is provided with an insertion rod with an internal thread, the insertion rod is inserted into the insertion hole to connect the first housing 11 to the second housing 12, and then a screw is passed through the insertion hole and locked with the internal thread in the insertion rod, thereby fixing the first housing and the second housing. The housing is detachably designed to facilitate the maintenance and replacement of parts and components later.

An upper end of the housing can be designed to take the shape of a handle to facilitate use.

The housing is provided with a chamber 13 that is sized to fit the blade holder 2, and the chamber 13 is internally provided with a pushing-type locking device 5, as shown in FIG. 4. The pushing-type locking device includes a pushing block 51 and a sliding groove 52 fixedly connected on an inner wall of the chamber for pushing the pushing block to slide. One end of the sliding groove is open, and two pairs of clamping grooves protruding outwards are arranged at the other end of the sliding groove, i.e. first clamping grooves 521 and second clamping grooves 522 respectively. A clamping portion 511 adapted to the clamping groove is arranged at one end of the pushing block 51, and the position of the pushing-type locking device is limited when the clamping portion enters the clamping groove. Specifically, when the clamping portion 511 enters the first clamping groove 521, it is an unlocking position of the pushing-type locking device; and when the clamping portion 511 enters the second clamping groove 522, it is a locking position of the pushing-type locking device. Rectangles are arranged at upper and lower parts of an outer surface of the blade holder, and two long sides of the rectangles form a fixing groove 21 with one open end. The position and width of the fixing groove 21 match those of the pushing block 51. The pushing block enters and exits the fixing groove through an opening of the sliding groove. When the pushing block 51 is pushed into the fixing groove 21, it is corresponding to the locking position of the pushing-type locking device 5 and the housing 1 is connected to the blade holder 2. When the pushing block 51 is pushed away from the fixing groove 21, it is corresponding to the unlocking position of the pushing-type locking device 5 and the housing 1 is disengaged from the blade holder 2. A push button 7 is arranged on an outer surface of the housing. A through hole is arranged between the chamber 13 and the outer surface of the housing. The push button 7 is approximately T-shaped, its horizontal portion protrudes upwards to form a grip and has a length greater than that of the through hole, and its vertical portion penetrates into the chamber through the through hole and is connected to the pushing block. A limiting groove 71 for pushing the push button to slide is arranged on an outer surface of the housing. Through the above technical solution, the detachable connection between the housing and the blade can be achieved by the pushing-type locking device 5. Specifically, the pushing block 51 can be driven to slide together by pushing the push button 7 on the outer surface of the housing, so that the pushing-type locking device is switched between the unlocking position and the locking position. When the pushing-type locking device is in the locking position, the housing is connected to the blade holder and the blade thereon. When the pushing-type locking device is in the unlocking position, the housing and the blade holder are disconnected, and the blade holder and the blade thereon can be disassembled.

One end of the blade 3 is mounted in the blade holder 2. According to an embodiment of the utility model, the blade holder is equipped with three rows of blades arranged in parallel. The blades located in the blade holder are separated by partitions 22; the blade holder is internally provided with mounting posts; and the blades and the partitions are both provided with perforations, and are sleeved on the mounting posts through the perforations so as to be fixed in the blade holder. The part of each row of the blades that is not mounted in the blade holder is divided into blade needles arranged at equal intervals. The blade needles have 45-degree sharp corners at lower ends thereof, and the sharp corners of the adjacent blade needles have opposite inclination directions, so that the meat tenderizer is sharper and can cut muscle fibers more efficiently.

Guide posts 6 are arranged on both sides of the blade. The inside of the guide posts is hollow. The guide post is provided with a clamping block 61 at one end thereof and a clamping post 62 at the other end thereof. A tail part of the clamping post takes the shape of an inverted hemisphere. The housing is internally provided with a limiting cavity 14 at a position corresponding to the guide post. The guide post 6 is clamped into the limiting cavity 14 through the clamping block 61, thus enabling the connection with the housing. The limiting cavity is internally provided with a return device 8 which includes a limiting block 81 and a compression spring 82. The limiting block 81 is T-shaped, its horizontal portion abuts on an inner wall of the limiting cavity, the compression spring is sleeved on a vertical portion of the limiting block, and the other end of the compression spring is placed inside the guide post, thus enabling the connection with the guide post.

As shown in FIG. 5, buckling devices 9 are arranged on both sides of the baffle plate at positions corresponding to the clamping posts, the buckling device includes a spring 91 and a buckling body 92 with an opening in the middle thereof, the buckling body 92 has limiting holes on both sides thereof, the spring 91 has one end abutting on an inner side wall of the baffle plate and the other end abutting in the limiting hole, an upper end of the buckling body 92 protrudes upwards to form a button 921, the opening of the buckling body takes the shape of one large circle intersecting with one small circle, with the large circle on the top and the small circle at the bottom, the radius of the large circle is greater than that of the tail part of the clamping post, the radius of the small circle is smaller than that of the tail part of the clamping post, the baffle plate 4 is provided with a through hole 41 at a position corresponding to the small circle, and the clamping post 62 of the guide post passes through the through hole 41 on the baffle plate and is connected to the buckling device 9. The baffle plate is also provided with a slot 42 for the blade to pass through.

Through the above technical solution, when the button is pressed down, the buckling device 9 compresses the spring 91, the large circle is moved into the position of the through hole, and then the guide post is placed into the buckling device through the through hole. When the button is released, the spring is reset and the small circle returns to the position of the through hole. Since the radius of the small circle is smaller than that of the tail part of the clamping post, the clamping post 62 is locked in the buckling device, thus enabling the connection between the guide post 6 and the bottom plate 4. When it is necessary to disassemble the guide post from the bottom plate, the button is pressed again in the same step, then the large circle moves to the position of the through hole, and the clamping post is disengaged from the large circle. Those skilled in the art can also come up with other forms to enable the detachable connection between the guide post and the baffle plate.

During use, a user first connects the blade holder 2 and the blade 3 thereon to the housing 1, and at this time, the pushing-type locking device 5 is in the locking position; and the guide post 6 is connected to the baffle plate 4. The meat tenderizer is placed above meat ingredients. The user holds the upper end of the housing and presses the upper end down, the compression spring 82 contracts, the guide post 6 moves towards an upper part of the limiting cavity 14, the housing 1 moves downward with the blade 3, and then the blade 3 passes through the slot 42 on the baffle plate to directly penetrate into meat and cut the fibrous tissue of the meat. When no external force is applied to the housing, the compression spring 82 is reset, and the guide post 6 moves towards a lower part of the limiting cavity to return to the original position.

The housing is provided with several drainage channels 10 on both sides thereof, and stop strips 101 are arranged in the housing at positions corresponding to the drainage channels. The purpose of the drainage channels 10 is to discharge the water retained in the housing. Moreover, the stop strips can prevent foreign matter from entering the housing through the drainage channels and therefore have the function of dust prevention.

The meat tenderizer also includes a protective cover 102 which is connected to a lower end of the housing, and an antislip strip is arranged on an outer surface of the lower end of the housing to prevent the protective cover from falling off. The blade, the guide posts and the baffle plate are wrapped inside the protective cover, thereby reducing the risk of accidental injury by the blade while protecting the parts in the protective cover.
